3G/4G Menu

Where is the hidden menu for the 4g preferred setting? Isn't there a hidden setting menu. My phone tried to stay on edge. My little brother has a blaze and is right next to me and his is on 4g and mine is on edge....
I still have IMEI so that isnt the issue. :good:

go to the play market and download phone info

Should it be set to gsm/cdma auto(Prl)?
It was on gsm auto (Prl).
It seems since I flashed a Rom and then did my Nan restore to stock rooted it preferred edge over 4g.

no if you want it to prefer 4g ovr edge then you have to have it set to wcdma preferred. that's tmobile's 4g! and then when it isn't available it will simply go to edge. that's definitely your best bet.

I did that now. It still was sticking on edge. I then switched it to wcdma only and it switched right to 4g. Thing is on edge it had full bars. 4g only two. I wonder if that's why it stayed on edge. Anyone know?

So I'm visiting family in Toms River NJ and I have full bars of Edge service, but no 4G service. Should I try switching network settings or what ??

try wcdma preferred. It helps stay on 4g. There may not be 4g where you are. Might want to check on that.

So I did this same thing and it's telling me I'm on 3G.
When I was on completely stock ROM out of the box, I was on "4G" all the time.
Now, every ROM I've flashed to test out which one I like, it displays 3G BUT whenever I click on a link it switches to H+. Then when that link is done loading it switches back to displaying 3G. Am I correct in assuming that it is supposed to do this?
Edit - After reading the NEXT post while I was doing my search, it seems that I was correct. :]

correct you are. while It's accessing data it goes to H+

I have my set to wcdma preferred. Keep in mind this setting might use more battery because it's constantly looking for four g signal rather than two g or three g

If I'm not mistaken, on stock it will always show 4G, even on 3G.
A lot of custom roms change this so it tells the truth. That's why you see 3G or H/H+.

Signs of 4g lte???

I'm hoping that sprint is actually adding 4g lte in my area. My phone has had 1x for 12 hours now but with decent data speeds? Anyone else go through this before you received lte

4g in LI is a secondary market, but I bet they are already starting to change to Network Vision. The whole Island will have 4G LTE by mid to late 2013. As soon as the NYC market is finished your area will get a LTE bath.
I saw on the S4GRU map that Queens and parts of Hempstead was already being worked on for Network Vision.

yeah ive been hoping those predictions are true... i work in queens and am in NYC often, but haven't had to much 1x experiences there yet...
hear NYC should be by the end of this year, so hopefully wont have too long of a wait...

Dying for some LTE in the city and Bx, my phone is pretty much like a dummy model when I'm at work.

If that is CM I see it might just be a bug where it isn't displaying 1X/3G properly.....

4G and 3G are not actually different for Tmobile.
Wikipedia article on Evolved HSPA
So then, the question is how to turn off DC hspa. Which is probably not accessible through the maintenance menus.
But for many real world value metrics I don't know what you would gain.

I'm wondering if the OP came from Sprint? Sprint's 4G was a separate (battery sucking) radio that you could turn on and off and needed to in order to protect the battery usage.

4g on TMo isn't like LTE, it's not a separate modem to turn off like AT&T, VZW, or sprint. It's really a hopped up version of 3G. Your choices are 3G/4G or Edge.

On T-Mobile, there is no real differentiation between 3G and 4G. Both operate on the same spectrum. The only difference is the speeds. However, that is controlled, not by your phone, but by the tower you're connected to. It's easier to look at it as the same exact technology. For the purpose of this conversation, there is no more T-Mobile 3G. It's all 4G, or HSPA+, service now. The 3G brand has been retired in favor of the 4G moniker.
To put it all simply, 3G is the same as 4G on T-Mobile. To turn off 4G, you would drop down to 2G, or EDGE/GPRS, service.

And if you still want to do it.....go to settings - more settings - mobile networks - network mode and you can select "GSM only".
Strangely enough....there are a couple areas around where i live that my phone will show a 4G connection and absolutely refuses to open anything. I've found that if i switch to the "GSM only" option in those areas that at least i can get it working... slowly, but better than nothing.
Had the same issue with my previous phone. (G2) weird phantom 4G zone. :-/

fix for disconnect from 3g network

For anyone having issues with getting disconnected from 3g network. If you find that you are continuously getting disconnected from the 3g network on Sprint, goto your network settings and change your preferred network setting from lte/cdma to CDMA only. That should keep you on the 3g network without having to continuously reboot all the time. It's not a problem with your Rom I think it's an issue with the lte network. Being that it may not be up and running in your town. Yes they are advertising it but it is not online across the entire country yet.

Mobile data not working

has anyone had the issue where their phone won't connect back to 3g data?
when I reboot my phone 3g will work until wifi kicks in. after I turn wifi off 3g comes back, I can call and text but will not download any data.
I have tried Odin back to stock. wiped everything including recovery. I have tried flashing every combination of modems and kernels. all same.
however one thing I will note. I have not been able to get a successful modem flashed in Odin. it keeps failing. so I flash in twrp.
I also wiped the activation data via ##732# or something like that. had sprint reactivate my phone too..
perhaps someone could shed some light on this?

I just got my Note 2 like 5 days ago and mine does the same thing. Its very annoying and its gonna be exchanged today for that and other reasons.
Sent from my SCH-I535 using xda premium

hmm. I wonder if it's network related..
is your phone stock?
-Wizzle

Okay here is the skinny. It is network related. My wife's stock s3 does the same thing. If you are in an area without lte and your phone under mobile settings is selected to lte/evdo/cdma it will connect to ephrd13. Which is enhanced 3g. When you come off wifi or a phone call sometime it will not reconnect. You can toggle data a few times and it will reconnect.
To solve this issue, under mobile settings I select evdo only setting being that I do not have lte in my area. There is no change in speed between the 2 3g networks.
This info is from self diagnosing the rooted note 2, a stock photon, and a stock s3.
I have had sprint reset the phones as well as the ##data# trick.

When I say evdo only I meant cdma only. Ehrpd13 is the handshaking 3g for lte. Some areas have lte in the towers but no ehrpd13 so the lte is not turned on yet. Basically ehrpd13 and lte are like cookies and cream lol.

Sent from my SPH-L900 using xda premium

When the 4g network matures as it will the 4g will get better as the 3g.
You can always go to I think s4gru.com. That site shows when and where lte will become available. Plus they will be able to help you better there than xda.
As for sprint customer service, they are laughable at best. 4 people I spoke with didn't know what ehrpd13 was lol.
